Hubert Lawrence | Standing together in the face of pain

first_img BUSY SCHEDULE When Cavahn McKenzie died at the end of a 2014 cross-country race in Trinidad and Tobago, it was awful for St Jago High School. His teammates got the news as they contested the Gibson-McCook Relays and it crushed them. Their schoolmate, teammate and friend had left them for international duty and, tragically, never returned home. Unfortunately, the same kind of tragedy has visited St George’s College with the equally sad passing of their Manning Cup football captain, Dominic James. This time, there was a cruel twist as he died during a Manning Cup game, with spectators there to witness his last moments. Truly, for all present, it must have been a terrible moment. These gruesome things scarcely happen in sport which is entertainment for many. Yet, the grief felt by everyone has to jump-start new provisions to safeguard the health of athletes at every level. In this regard, the early announcement about heart-screening high-school student athletes becoming mandatory is most welcome. After McKenzie’s untimely passing in Trinidad and Tobago, Team Jamaica Bickle, that wonderful group of Penn Relay benefactors, has assisted with screening athletes and by donating machines – known as defibrillators – which are designed to restart hearts. This may have to become standard for high school, club and national sport. As a precaution, it may also be wise to extend the schoolboy football season into January. The present season squashes the Manning and daCosta Cup, the Walker Cup and Ben Francis KO and the FLOW Super Cup into a rapid-fire schedule that has teams playing three times in seven days, with complications if rainy weather intervenes. The schedule gets busy for the top teams, when the later stages of the Corporate Area Manning Cup and the rural area daCosta Cup commingles with the Super Cup and the Corporate Area Walker Cup and the rural area Ben Francis knockout competitions. The congestion is no one’s fault. There are far more eligible schools than in bygone days. Luckily, the solution is simple. The schedule could be relaxed by moving the Super Cup into January, the first month of the Easter term. That is a matter for another day. Right now, the Light Blues need our love and support. As with the St Jago case, James’ family and his teammates at St George’s College need counselling and the steadfast embrace of every Jamaican. At times like these, the only choice is to stand together. – Hubert Lawrence has made notes at trackside since 1980.last_img read more

Azkals near semis berth

first_imgWill you be the first P16 Billion Powerball jackpot winner from the Philippines? BACOLOD CITY—The latest in the long line of talents hailing from the country’s football hotbed, Barotac Nuevo, delivered a goal that could prove crucial to the Philippines’ hopes of reaching the knockout stage of the AFF Suzuki Cup.On a rainy Wednesday night at Panaad Stadium, Jovin Bedic came off the bench to rifle home the equalizer as the Azkals salvaged a 1-1 draw with Thailand to stay on track for a place in the semifinals.ADVERTISEMENT Gretchen Barretto’s daughter Dominique graduates magna cum laude from California college Bedic’s deflected effort in the 82nd minute cancelled out an earlier strike from Supachai Jaided as the Philippines remained level with Thailand with seven points in Group B. Another point against Indonesia in Jakarta on Sunday will be enough for the Philippines to reach the next round.The Azkals came into the match looking to end a 46-year winless spell against the Thais. And although they did not walk away with the maximum points, the battling performance was enough to impress coach Sven-Goran Eriksson.FEATURED STORIESSPORTSGinebra beats Meralco again to capture PBA Governors’ Cup titleSPORTSJapeth Aguilar wins 1st PBA Finals MVP award for GinebraSPORTSGolden State Warriors sign Lee to multiyear contract, bring back ChrissIn truth, the Azkals could have gotten more from the match had they been more clinical on goal as Phil Younghusband and Patrick Reichelt missed good chances in the first half.“First of all I think we played very well 90 minutes,” said Eriksson. “We were the better team out there.

The Evolution of Electrical Engineering:  An Imaginary Tale

first_imgNerves carry electrical impulses.  Ipso facto, they are subject to laws of physics concerning conductance, capacitance, and resistance.  Getting a signal from one end of an animal to the other in time can be a matter of life and death.  In order to maintain optimum levels of electrical conductivity to meet their lifestyle requirements, animals possess numerous adaptations to increase throughput.  In a paper in Current Biology,1 D. K. Hartline (U of Hawaii) and D. R. Colman (McGill U, Quebec) described how these adaptations fall into two main categories:Nervous systems have evolved two basic mechanisms for increasing the conduction speed of the electrical impulse.  The first is through axon gigantism: using axons several times larger in diameter than the norm for other large axons, as for example in the well-known case of the squid giant axon.  The second is through encasing axons in helical or concentrically wrapped multilamellar sheets of insulating plasma membrane – the myelin sheath.  Each mechanism, alone or in combination, is employed in nervous systems of many taxa, both vertebrate and invertebrate.  Myelin is a unique way to increase conduction speeds along axons of relatively small caliber.  It seems to have arisen independently in evolution several times in vertebrates, annelids and crustacea.  Myelinated nerves, regardless of their source, have in common a multilamellar membrane wrapping, and long myelinated segments interspersed with ‘nodal’ loci where the myelin terminates and the nerve impulse propagates along the axon by ‘saltatory’ conduction.  For all of the differences in detail among the morphologies and biochemistries of the sheath in the different myelinated animal classes, the function is remarkably universal.Hartline and Colman went on to describe how the insulation provided by myelin increases throughput dramatically:Myelin sheaths are frequently associated with rapid reactions, especially in invertebrate taxa.  For fibers of a few microns or more in diameter, myelin speeds the conduction of nerve impulses by a factor of ten or more compared to unmyelinated fibers of the same diameter.  This increases the nervous system’s information processing capacity and delivery speeds, decreasing reaction times to stimuli, increasing temporal precision, more closely synchronizing spatially distributed targets (such as different regions of a muscle sheet), and providing for shorter delays in feedback loops (for example in muscle control).  Because less current is needed to satisfy the charging needs of myelinated fibers, mean sodium channel densities averaged over the length of a fiber are much lower than for unmyelinated ones.  This results in a smaller ionic imbalance that must be restored after an impulse passes and confers a several hundred-fold improvement in metabolic efficiency for recouping the energy cost of nerve impulse traffic.  For a nervous system such as ours, which already accounts for 20% of the body’s resting metabolic energy budget, this is not an inconsequential advantage.  Another advantage is economy of space: to achieve the same ten-fold improvement on conduction speed through increasing axonal diameter, axons would have to be 100 times larger (with a comparable scale-up in soma size to accommodate the metabolic needs).  Imagine yourself with a 100-fold thicker spinal cord!    The authors were also interested in how these adaptations could have evolved.  Consider the scope of their puzzle:Both mechanisms (axon gigantism and insulation) are dispersed throughout the animal kingdom.There are great evolutionary distances between similar adaptations.There are no transitional forms.There are no clues from fossils.So despite confidence that these adaptations did evolve, they admitted they had only speculation about natural selection might have achieved it:So ancient is its evident appearance in each of these lines, and so sophisticated its morphological and chemical structure, that its exact origin in most of those lines is hard to establish.  Even in vertebrates there is a great evolutionary distance between the unmyelinated hyperoartia (lampreys) and the gnathostomes.    The initial steps in the evolution of myelination may not, however, be that difficult to reconstruct.  Electrically sealing together two apposed membrane surfaces over a small region of axon decreases its transverse capacitance and proportionately speeds impulse propagation along it.  The sealing can be achieved by narrowing the conductive space, either cytoplasmic or extracytoplasmic, between adjacent axonal and/or glial membranes … or through impermeable specializations at margins, for example precursors of septate junctions.  Even the random sealing of patches of single-layer glial membrane over half of an axon’s surface is predicted to increase conduction speed by about 20%.  Once such a process has started, it is not difficult to imagine a sequence of small improvements driven by natural selection that would ultimately lead to the complex structures we see today.  This is speculative, however; no cases have been described so far of ‘intermediate stages’ in extant groups.  Developmental sequences, the lack of fossil records and the paucity of candidate molecular precursors so far identified have made the task more difficult.  Perhaps better insight will be gained through increased attention to myelin evolved in the invertebrates. (Bold and underlining added.)1D.K. Hartline and D.R. Colman, “Rapid Conduction and the Evolution of Giant Axons and Myelinated Fibers,” Current Biology, Vol 17, R29-R35, 09 January 2007.These guys started right off the bat with the BAD strategy (brazen assertions of dogmatism): “Nervous systems have evolved…”  Ahem–there are a lot of people who do not accept that.  Your evidence, please?  Some fossils, perhaps?  A long sequence of intermediate steps, each with increased survival value?  A clear phylogenetic pattern?  None of the above.  So here is their argument: “it is not difficult to imagine…”    If you thought science was about evidence and proof, welcome to the Storybook Land of the Darwinist (see 12/22/2003 commentary).  Instead of launching into another sermon against imagination in science as a substitute for evidence, this time we will let the Good Book do it for us.  Substitute Darwin and natural selection where appropriate:God saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually. (Genesis 6:5)the imagination of man’s heart is evil from his youth. (Genesis 8:15)Why do the heathen rage, and the people imagine a vain thing? (Psalm 2:1)they imagined a mischievous device, which they are not able to perform. (Psalm 21:11)They also … imagine deceits all the day long. (Psalm 38:12)Which imagine mischiefs in their heart (Psalm 140:2)Deceit is in the heart of them that imagine evil (Proverbs 12:20)neither shall they walk any more after the imagination of their evil heart. (Jeremiah 3:17)But they hearkened not, nor inclined their ear, but walked in the counsels and in the imagination of their evil heart, and went backward, and not forward. (Jeremiah 7:24)But have walked after the imagination of their own heart, and after Baalim, which their fathers taught them. (Jeremiah 9:24; for fun, try substituting Darwin for Baalim here)Yet they obeyed not, nor inclined their ear, but walked every one in the imagination of their evil heart (Jeremiah 11:8)This evil people, which refuse to hear my words, which walk in the imagination of their heart (Jeremiah 13:10)And ye have done worse than your fathers; for, behold, ye walk every one after the imagination of his evil heart (Jeremiah 16:12)And they said, There is no hope: but we will walk after our own devices, and we will every one do the imagination of his evil heart. (Jeremiah 18:12)Thou hast seen all their vengeance and all their imaginations against me. (Lamentations 3:60, 61)What do ye imagine against the Lord? (Nahum 1:9)He … hath scattered the proud in the imagination of their hearts. (Mary, praising God in Luke 1:51)Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened. (Paul, in Romans 1:21)Paul continues, “professing themselves to be wise, they became fools.”  Here you have witnessed academic elite scientists claiming, out of thin air, without any evidence, that sophisticated electrical engineering emerged by mistake!  Does the shoe fit, or what?  They have glorified their own speculations.  They have imagined a fable that runs 180 degrees contrary to the evidence.  They have totally refused to bend their stiff necks to alternative explanations, like intelligent design.  They have shown themselves to be dogmatist wolves in scientist sheep’s clothing, walking after the imaginations of their own foolish hearts.    So we end with more advice from the Apostle Paul: words that would have been understood as a mission statement by many of the founders of science: “Casting down imaginations, and every high thing that exalteth itself against the knowledge of God” (II Corinthians 10:4).(Visited 10 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

American, Qantas denied more time to make trans-Pacific submission

first_imgAmerican Airlines and Qantas will not be allowed additional time to respond to a US Department of Transportation decision to deny permission for an expanded trans-Pacific alliance.In a sign the DoT is taking a hard line on the issue, it refused a joint request by the airlines to extend the deadline for comments on its November 18 tentative decision not to grant the partners anti-trust immunity from December 2 to December 20. The airlines also asked for the deadline for answers to their comments be extended to December 30.Their request came after the  DoT issued a show cause notice seeking submissions on its decision to deny the carriers anti-trust immunity after finding the alliance would harm competition.The airlines had applied to expand their joint business agreement to a full alliance similar to the one Qantas has with Gulf carrier Emirates that would allow them to operate “metal neutral’’ joint flights alongside each other.This would allow them to coordinate functions such as scheduling, network planning, sales, customer services and capacity decisions, something the carriers argue would allow them to more effectively compete across the Pacific and expand services.In its latest letter,  the department said the carriers  had offered no compelling reason to alter the response schedule and it did not see any.It said the facts and issues involved had been well developed and argued by -argued al issues involved have been well developed and argued by the parties to the  proceeding, including the applicants.It also dismissed a claim by the airlines that they needed more time to consider the reasoning and analysis behind the decision as well as  the potential implications for their businesses.“ We find these arguments unpersuasive,’’ the department said.  “The underlying issues and facts, and accordingly the reasoning and analysis, are relatively straightforward, and the show-cause order raised no issues that have not been obvious during the course of the proceeding.“Moreover, any implications for the applicants’ business interests have always been inherent in the possibility of denial of the application, a possibility that always exists until a final decision in any proceeding of this kind.“Given our decision here, we find that the need for resolution of this issue outweighs any benefit of awaiting answers to the motion.“Accordingly, we deny this motion, and are acting with dispatch to remove any ambiguity with regard to the procedural schedule for the benefit of the applicants and other parties alike, giving them the maximum amount of time to prepare their submissions. ‘’American signalled last week it would object to the proposed decision against the alliance, which has been given the green light by regulators in Australia and New Zealand.“This represents a significant departure from prior DOT decisions, which have long recognized the pro-competitive benefits of combining complementary international networks,’’ it said at that time.“Other airlines have the significant competitive advantage of antitrust immunity in the U.S.-Australasia market. With the same opportunity, American and Qantas will be able to compete more effectively and increase consumer benefits in the market.’’last_img read more

Mahalo Pivots to Focus on Video-Based Learning

first_imgA Web Developer’s New Best Friend is the AI Wai… Tags:#E-Learning#NYT#Video Services#web#YouTube 8 Best WordPress Hosting Solutions on the Market Related Posts audrey watterscenter_img Serial entrepreneur Jason Calacanis has just announced Mahalo 4.0, the latest pivot for his company that has now moved from being a “human-powered search engine” to a Q&A site. The new Mahalo, unveiled at the Digital Life Conference today, will be focused on creating how-to video content.The goal, according to Calacanis, is to create thousands of original, high-quality videos each week. These will be supplemented with additional text as well as real-time Q&A offerings. As Dan Frommer from Business Insider describes it “Think of it as Howcast (how-to-video) + Quora (Q&A) + About.com (a more structured Wikipedia).”Learning to PivotIn his presentation at DLD today, Calacanis narrated the story of Mahalo’s multiple pivots. Founded in 2007, Mahalo did a good job with the human-powered search, argues Calacanis, but just couldn’t keep up with the adjustments that Bing and Google were making to improve their own search results. And so Mahalo continued to iterate, improving in the areas in that Calacanis said its users were already drawn to. At first, that was the “answers” component. And now it’s this “how-to” video aspect.All About the LearningBut just as “search” and “answers” are both quite crowded fields, Mahalo is entering into a space – video-based learning – where it will have several competitors. There are a number of popular and well-trafficked how-to sites, including Howcast and eHow. As Mahalo is providing more than just video – maintaining the real-time answers component, for example – it will be interesting to watch how this pivot may impact some new companies who are trying to build video-focused casual and lifelong learning sites – companies like Udemy, for example. How will user-generated how-to and educational videos fare against Mahalo’s slick production value?So will this pivot work for Mahalo? Calacanis insists the company is in a strong financial position. And he says that traffic is good, too; the company currently has about 12 million monthly uniques, and this new venture continues the company’s partnership with YouTube, which generates quite a bit of ad revenue.So studio-made and expert-filled videos may be what gives Mahalo an edge on its competitors. Or – despite the move away from the “search engine” as the focus of Mahalo – this could all just come down to one big SEO battle. It’s clear with today’s announcement that Mahalo is putting a lot of resources into developing a rich library of content. Will this drive traffic? And will learners be drawn to this site?
